There's not much MythTV can do about it. It can only work as well as
the information it is given. Garbage in, garbage out. If you want, you
can add a user job that checks the resolution of a recording file. If
the show is marked in the guide data as HD, but the file is not, mark it
for re-recording and/or delete it. If it's upscaled SD, I suppose you
could check for the VBI mess at the top of the screen, or poor
underscaling of the video.

You can do that, or you can mark a channel as hidden and remove the
xmltvid, which will have the same effect. Of course in your scenario it
wouldn't make much of a difference.

Yes, but considering he already has an SD copy of the episode, there is
nothing to be lost in recording another SD copy, mistakenly thinking it
is HD.

You get those flags from Schedules Direct, Schedules Direct gets them
from Tribune Media Services, and Tribune gets them from each individual
affiliate. You can complain to SD, who will complain to TMS, who may
complain to the affiliate, but it all comes down to the fact that TMS
gave you the most accurate information it could, which was wrong because
the affiliate lied. There's not much recourse against such a situation.
